UK Looks to Rivers for Heat Pump Energy

Linda Hardesty

A map published by the UK government finds that there are around 40 urban rivers and estuaries in Britain that could provide large-scale renewable heating supplies to local communities through water source heat pumps, instead of traditional gas-fired or electric heating. Water source heat pumps operate by taking heat from the water and feeding it   …Continue Reading


Slovakian City Uses Waste-to-Energy System for Heating

Linda Hardesty

ElectraTherm commissioned 10 Green Machine 4400s for the city of Levice, Slovakia in June 2014. ElectraTherm’s Czech distributor, GB Consulting, facilitated the deployment of organic rankine cycle (ORC) systems on a centralized district heating system in Slovakia as a means of increasing on-site efficiency and generating clean energy. To date, the site has accumulated over   …Continue Reading


New Technologies, Fuels Enhance Viability of $10B District Heating Market

Karen Henry

Traditionally, buildings are fueled by petroleum, natural gas, electricity and coal, but an opportunity exists to decouple the energy source from the building, through district heating (DH) networks. According to a report from Lux Research titled “Heating for the Future: Identifying Global Hotspots for District Energy,” DH can deliver cost gains of up to 74   …Continue Reading

The utility industry’s research arm has started studies of the rapid rise of distributed energy resources (DER) and how best to integrate them into the grid. The Electric Power Research Institute (EPRI) is studying the transformation of the electric power grid brought about by large numbers of rooftop solar panels and high tech microgrids. Few   …Continue Reading


Duluth May Update Downtown’s Central Heating

William Opalka

A centralized plant that uses water from Lake Superior to heat 180 downtown Duluth buildings is due for an upgrade. The plant, which has operated for 81 years, draws frigid lake water to be heated by a coal-fired furnace and then pipes steam to downtown businesses. The plant is inspired by a similar system in   …Continue Reading
